Mag1 0w20 vs Mobil 1 Extended Performance

[Larkin]

I found the spec. on Mag1 0w20. What do you think of the moly #? How does the Mag1 oil compare to Mobil 1 Advanced Fuel Economy, Mobil ep or Toyota oil. I'm going to use it in my wifes 2014 Toyota 2.5. After Toyota service runs out at 30 000.

There should be a virgin test for the Toyota TGMO here somewhere on BITOG.

I imagine Mag 1 is a gpIII. Mobil 1 Advanced Fuel Economy is a gpIII with some kind of GP4? W.A.G thoughM1 link

Very nice pour point etc.

 

[MinamiKotaro]

Mag1 is excellent. I actually prefer it to Mobil for purely subjective reasons: the way the engine sounds, feels, etc.

I doubt your engine would ever know the difference between them.

Well, according to pqiamerica.com Mobil 1 Advanced Fuel Economy has noticibly lower NOACK, higher viscosity @ 100ºC, higher viscosity index, and lower viscosity @ -35ºC. I would hope that EP had even better specs than AFE, but I don't have any proof one way or another.

Now, just because it is noticeably doesn't mean that it is meaningful. YMMV.

Mobil uses higher quality base stocks with more PAO (Group IV) and Group V - especially in the EP line that the OP referenced.

They also buy in higher volume and blend a better synthetic product (than Mag 1) for a fair price. Mobil is a major supplier of base stocks to other blenders around the world.

Pennzoil likewise uses excellent base stocks in their Platinum and Ultra lineup that are likely superior to Mag 1.

With that said, Mag 1 is a good serviceable (very average) Group III oil suitable for many applications.

With a -54f pour point, there's gotta be some POA in the mix. G III oils usually don't have a PP that low on their own.

 

[147_Grain]

Mobil EP is -65.2F., which is 18% lower PP than Mag 1.

You can't judge an oil solely off the pout point alone, mrv specs are much more useful in cold temps. Is Mobil 1 Extended Performance the better oil? Most likely, however at a 5-7.5k oci will there probably not be any difference.

In all honesty, who in their right mind is actually going to be out in temps -54f or below. Let alone there are very few spots in the contiguous 48 states that will ever reach an ambient temp that low.

from reading Mobil I EP is the only mobil I using some PAO real synthetic group IV. that Mag I noack is poor. 5-20's are usually stronger oils than 0W-20's. check out the pennzoil platinum with pure plus tech, pretty good stuff for a 5-20 oil. i do not believe in using any xw20 oils by the way, they are for the EPA ratings not your engine life!!

Thanks for all your input. I'm going with Mobil 1 Advanced Fuel Economy 0w20. Now I need a oil filter. Looking at
